采用接收与协作双重分集的系统性能分析

Performance Analysis of the System Adopting Dual Diversity of Receiving and Cooperation

研究了一种同时采用两种分集技术的通信方式。在给定的工作环境中,分析了双重分集系统的工作原理,以及信号的传输与接收的过程。并把本文研究的双重分集技术与单纯的空间分集、单纯的协作分集两种技术作了比较。最后通过理论分析与数值计算的结果表明,与单纯的协作分集和单纯的空间分集相比,本文研究的双重分集系统性能更为优越。

A new communications mode which adopts two diversity techniques simultaneously is studied. In a specific operation environment, the principle of the system, and the process of transmitting and receiving of the signal is analyzed. The studied dual-diversity system is compared with single space diversity system and single cooperation diversity system. Finally, based on the theory analysis and numerical calculation, the scheme of the studied dual-diversity system in this paper is superior to those of the other two techniques in performance.
